Nrrn STATES HENRY RT. VAUGHAN, OF BELFAST, IRELAND.

BRICK-KILN.

SPECIFICATION forming part of Letters Patent No. 591,065, dated October 5, 189'?. Application filed September 30,1896. Serial No. 607,410. (No model.) Patented in England October 3l, 1895, No. 20,540..

To CLZZ'wton/z/ it may concern:

Be it known that I, HENRY ROBERT VAUGHAN, a subject of the Queen of Great Britain, and a resident of the city of Belfast, Ireland, have invented certain new and uscful Improvements in Continuous Burning Kilns for Burning Bricks and other Clay Goods and also for Limes and Cements, (patented in England on October 3l, 1895, No.

pended three explanatory sheets of drawings,

Figure l is a longitudinal section of the kiln on the line A A of Fig. 2. Fig. 2 is a plan of the kiln with one-half shown in section on the line D D, Fig. l. Fig. 3 is a vertical cross-section of the kiln onthe line B B, Fig. 1. Fig. 4t is a vertical cross-section of the kiln on the line C C, Fig. 2. Fig. 5 is a side elevation of the kiln. Fig. 6'is an end elevation of the kiln. Fig. 7 is a ground plan of the kiln.

Referring to the drawings, whereon the same reference-letters wherever repeated indicate the same parts, a a', b b', and c c' are the rectangular chambers which, as shown, are arranged in two rows beside one another.

d d are end or division walls between the two sets of chambers, and e the side walls separating chamber from chamber. Passages f are made in the walls e, while passages g are made in the walls e' of theend chambers.

Three longitudinal flues t' 7l t2 are made under the floor of; the kiln, one at each side and one at the center, as shown.

Each chamber has passage-ways h, communicating, respectively, with two of the iues above specified, such communication being between said chambers and the two flues half the distance to travel to the outlets, and

crushing and squabbing of bricks is also prevented. There are also two fines j j', which are arranged across the kiln, one at each end, and communicate by the passageways g with the end chambers a d and c c at both sides of the kiln. These fines convey the hot gases from the end chambers under lire on the one side to the end chambers on the other side, thereby making them regenerative and continuous in burning. The inlets and outlets g are provided with damers, so that the heat and `draft passing along the flues j from the one side can be diverted through any of the passages g to any part of the end chambers where required, thereby giving a full and complete control of the draft. Y

As will be seen from the dotted lines at Fig. 7 the three longitudinal flues z' c" 2 lead to the chimney Z.

A central hot-air flue n is also arranged in the top of the kiln above the iiue m, and this iiue has cross or branch lines fn', which communicate by means of the outlets and inlets o with the roof of each chamber. Each branch isv supplied with a damper p. These flues are arranged to withdraw the waste heat from the goods in theburned chambers and convey and circulate it along with the hot air to and through the green goods in the chambers newly filled. In this manner the green goods are dried or partially dried in the newly-lled chambers before they are directly connected with the chambers under fire. By thus utilizing the waste heat from the burned goods to dry the green goods sounder and better articles can be produced at a reduced cost. The colorv of the articles is also improved, as they are partially dried before being brought IOC into contact with the gases and sulfur emanating from the chambers under fire. TIncreased facilities for burning are also given.

The end branches n can be extended, as shown at q, Fig. 2, and be made to communicate with the passages r, leading to the flues vl i2. This is to enable hot air and waste heat to be conveyed from the fluen to the side llues e' i2 in order to heat the said lues, so as to improve the draft when connecting the chambers in which bricks are steaming on the one side with those on the other side ranged side by side, three parallel flues eX- in which the bricks are burning.

Having now fully described my invention,

what I claim, and desire to secure by Letters Patent, is-

1. A kiln having two rows of chambers arranged side by side, three parallel lines eX- tending longitudinally with the kiln, the intermediate iiue having its middle section between the two rows of chambers, and its two end sections below the chambers, and each chamber having passage-ways communicating respectively with the two lues nearest to said chamber, as set forth.

2. A kiln having two rows of chambers arranged side by side, three parallel lues extending longitudinally with the kiln, the intermediate liue having its middle section between the two rows of chambers, and its two end sections below the chambers, the end chambers communicating respectively with one side flue and one of the end sections of the intermediate iue, and the intermediate chambers communicating respectively with one side flue and the middle section of the intermediate ue, and transverse flues connecting the adjacent end chambers, all as set forth.

3. A kiln having two rows of chambers artending longitudinally with the kiln, and each chamber having passage-ways communicating respectively with the two lines nearest to said chamber, passageways between the adjacent chambers, and transverse passages jj communicating with the adjoining chambers at each end respectively of the kiln, all as set forth.

Signed at Belfast, county of Antrim, Ireland, this 29th day of July, A. D. 1896.
